Do Not Use Hydroxyzine for Alcohol Withdrawal!

We correctional practitioners get to see a wide range of medical practice as we review the medical histories of inmates arriving at our facilities. I myself have seen many prescribing practices that make me scratch my head. One example I have run into repeatedly is the practice at many jails of using hydroxyzine to treat alcohol withdrawal. It turns out that many jails do this. I am not talking about hydroxyzine as an adjunct or an add-on to the primary agent. I am talking about hydroxyzine being used as the primary treatment agent itself.

In my opinion, this is a mistake, and should be stopped.

Now I admit that there is room for dissention in medicine. Not all practitioners practice in the same way and there are many, many areas of medicine where there is no right answer. And it is true that hydroxyzine was used in the 1960’s to treat alcohol withdrawal. However, since then, medicine has discovered superior agents to treat this condition: the benzodiazepines. Today, hydroxyzine is the wrong agent for alcohol withdrawal. If your facility uses hydroxyzine as the primary treatment for alcohol withdrawal, you should change your protocol. There is no legitimate basis for this practice.

And the stakes are high. Alcohol withdrawal is serious business. People can and do die from alcohol withdrawal. In fact, in my experience in my own jails and reviewing cases elsewhere in the country, alcohol withdrawal is a common cause of death in jail. In fact, it may be the second most common cause of preventable deaths in jail, behind only suicide. Facing a potentially lethal problem, we should use the best therapeutic agent; not a second line, clearly inferior drug.

So what basis do I have to make the claim that hydroxyzine is a “clearly inferior drug” in the treatment of alcohol withdrawal? Well, I will give you not just one but six reasons not to use hydroxyzine for alcohol withdrawal:

There is no theoretical basis to use hydroxyzine for alcohol withdrawal.

Alcohol withdrawal occurs due to the following mechanism:

Alcohol acts in the brain by stimulating the gamma-aminobutyric acid (GABA) system (remember this–it’s important), which both inhibits excitatory brain impulses and enhances inhibitory ones. The end result of this is the generalized slowing of reaction times and movements that we all recognize as drunkenness. With high-level repetitive drinking, the brain makes more GABA receptors, so that the same amount of alcohol will exert less effect on the GABA system. This process is called “habituation.” Over the course of many years, the brain can make a lot of GABA receptors so that alcoholics can be amazingly tolerant of the effects of alcohol. My personal record is a guy I saw in the ER who was walking and talking intelligibly with a blood alcohol of 0.59.
However, when alcohol is suddenly withdrawn, all of these many GABA receptors are suddenly unoccupied, which causes the opposite effect of intoxication: Excitatory brain impulses are enhanced and inhibitory brain function is suppressed. The result is the classic symptoms of alcohol withdrawal. Just like there are various levels of intoxication in various individuals depending on the number of GABA receptors reacting to alcohol (from pleasantly “buzzed,” to slurred speech, to staggering, to comatose, to not breathing), there are also various levels of withdrawal symptoms correlating to how many GABA receptors are unoccupied. Like intoxication, withdrawal symptoms can range from mild (hand tremor only) to moderate (anxious, sweating and tachycardic) to severe (true Delirium Tremens) and death.

The key point here is that withdrawal is caused by exposed, unoccupied, irritated GABA receptors in the brain. The reason that benzodiazepines are so good at treating these symptoms is that they fit the GABA receptors! When you give a patient withdrawing from alcohol Valium or Librium, these drugs slide right into the empty GABA receptors and thus attack the problem of withdrawal at its source.

Hydroxyzine, on the other hand, does not fit the GABA receptors. Instead, hydroxyzine acts on the histamine H-1 receptor. This does cause a low level of sedation and neurological slowing, but since it does not act in any way, shape, or form on the GABA system, there is no theoretical way that hydroxyzine can perform as well as benzodiazepines in treating withdrawal—not even close.

There is no empirical basis for the use of hydroxyzine for alcohol withdrawal.

By “empiricism,” I mean direct studies proving the efficacy of hydroxyzine for alcohol withdrawal. I don’t mean to say that there are no studies at all. Hydroxyzine was studied in the context of alcohol withdrawal in the 1960s. About the best that can be said for the results is that hydroxyzine did perform better than placebo. Hydroxyzine, is, after all, a weak sedative. And, yes, hydroxyzine was used to treat alcohol withdrawal in alcohol rehab clinics in the 1960s. However, several other drugs were also used for withdrawal back then, including several antipsychotics (like Thorazine) and even paraldehyde. And I don’t see anyone using still using Thorazine for withdrawal.

The reason that hydroxyzine and the rest fell into disuse is this: as soon as benzodiazepines were introduced and tried as alcohol withdrawal agents, it was clear that they are vastly superior to hydroxyzine and everything else that had come before. For example, one of the very first studies using benzodiazepines for alcohol withdrawal was done in 1969 (reference here) and compared hydroxyzine to chlordiazepoxide (Librium). Librium kicked hydroxyzine’s butt—it was clearly the superior drug.

Based on this and many other similar studies, medical textbooks no longer recommended the use of hydroxyzine for alcohol withdrawal by the early 1970s, and instead recommended that “alcohol withdrawal should be treated with medications that have a similar chemical structure to alcohol”—like chlordiazepoxide. Two examples of textbooks published in 1972 that had already abandoned hydroxyzine in favor of chlordiazepoxide were The Merck Manual 12th ed. (from which the quote comes) and The Principles and Practice of Medicine 8th ed. (An interesting historical overview of the treatment of alcohol withdrawal can be found here).

Research since then has been done exclusively on benzodiazepines, agents such as phenobarbital and, more recently, seizure drugs like carbamazepine and valproic acid. However, since 1969, nothing, and I mean nothing has ever outperformed benzodiazepines as therapy for alcohol withdrawal. And hydroxyzine? Forgotten. I cannot find references to any studies using hydroxyzine for alcohol withdrawal since the 1970s. In those days, they were also using reserpine to treat hypertension. How many of us are still prescribing reserpine today? (If you are, I would like to hear about it)!

No current medical textbook nor any practice guideline recommends using hydroxyzine for alcohol withdrawal.

I know this because I spent some time and checked. Most of the textbooks and clinical guidelines do not even mention hydroxyzine at all among the various therapeutic options. All recommend using benzodiazepines as the primary treatment agent for acute alcohol withdrawal. A very few list hydroxyzine as a possible “adjunct,” meaning something that can be given in addition to the primary treatment agent. I personally don’t use hydroxyzine as an adjunct, however, for two reasons. First, there is no literature showing that this practice offers any benefit at all over treatment with benzodiazepines alone. Second, I don’t want anyone in my jails ever thinking that they can give withdrawal patients hydroxyzine instead of benzos.

Hydroxyzine is not used as a primary alcohol withdrawal agent in inpatient alcohol rehab centers outside of jails and prisons.

At least, almost every single alcohol rehab center and inpatient alcohol treatment center that I have ever come into contact with uses benzodiazepines. The one exception from my personal experience was a hospital that preferred to use phenobarbital for some reason. If you know of an inpatient alcohol detox center that uses hydroxyzine instead of benzos, I’d like to know about it! I personally doubt that such a facility exists.

You don’t have to be afraid to use benzodiazepines in a correctional setting!

I suspect that the reason that many jails have been using hydroxyzine instead of benzodiazepines to treat alcohol withdrawal is a desire to keep all controlled substances out of the jail for fear of abuse. This is a mistake for several reasons.

1. The benefits of benzodiazepine use for alcohol withdrawal (the best medication for a potentially life-threatening condition) clearly outweigh the potential for abuse.
2. Benzodiazepines used for alcohol withdrawal are only given for a short time—a few days at most. They should not be ongoing medications.
3. Patients being treated for alcohol withdrawal should be housed apart from the general population anyway, so that you can keep an eye on them. If they are not in general population, the risk of cheeking and sharing is very low. I have also found that such patients are highly unwilling to divert their meds, anyway.
4. You will not be able to keep benzodiazepines totally out of your facility. They are too useful in a variety of important ways, such as inmates who need chemical sedation and methamphetamine intoxication. Also, inmates who arrive at the jail with a long history of benzodiazepine use should not have their benzos discontinued cold-turkey. This is dangerous. (More on this later).
5. It is usually pretty easy to sort out patients who are truly withdrawing from those who are faking symptoms—in my experience anyway.

Finally, if, after reading all of this, you are still adamant that you will not use benzodiazepines, there are better alternative agents available than hydroxyzine.

I mentioned earlier that many other agents besides benzodiazepines have been studied as treatment for alcohol withdrawal. None has ever been found that is superior to benzos. However, several anticonvulsants have been shown to be superior to hydroxyzine and are mentioned as therapeutic alternatives to benzodiazepines in textbooks and treatment guidelines. The two most commonly named are carbamazepine and valproic acid. If you insist on using something other than benzodiazepines for alcohol withdrawal, look these up!

Summary:

1. Hydroxyzine is inferior to benzodiazepines for the treatment of acute alcohol withdrawal.
2. Benzodiazepines act directly on the GABA receptors responsible for withdrawal symptoms. Hydroxyzine does not.
3. Research done since the 1960s has clearly shown the superiority of benzodiazepines
4. Medical textbooks and treatment guidelines universally recommend benzodiazepines. None recommend hydroxyzine.
5. Inpatient alcohol treatment centers use benzodiazepine almost exclusively to treat withdrawal. None that I am aware of use hydroxyzine.
6. It is impractical and probably near-impossible to totally ban benzodiazepines from jails.
7. The possibility of abuse of benzodiazepines during short term use by alcohol withdrawal patients is small (in my opinion).
8. Carbamazepine and Valproic acid are both superior to hydroxyzine for treating alcohol withdrawal (though both are inferior to benzodiazepines).

As always, the views expressed here are my own. Feel free to disagree! I could be wrong. But if you do disagree, please comment and say why!

What do you use to treat alcohol withdrawal at your facility? Do you, by chance, use hydroxyzine? Please comment!

A combination taper of Librium, Dilantin and Thiamine are the ingredients of our primary treatment (with occasional Ibuprofen) – multivitamin for 2 weeks when that is completed.

That is combined with a structured screening process – and we’re not afraid to defer when clinically appropriate. Also, not aggressive about treating a ‘hangover’. More than willing to transfer to hospital when in-patient care is appropriate.

However, when the history of ETOH use and the clinical picture present a very mild picture (maybe what others may not even treat) we use the Dilantin, Thiamine and Hydroxazine. It gives us a bit of latitude between ‘whole hog’ and nothing.

We’ve used this ‘lower level’ of medications for a number of years without difficulty.

On reading of your great review of the issue; it certainly bears a thoughtful consideration – to continue as we are or not – yet, in those cases where a ‘mild sedative’ is appropriate – hydroxazine seems benign.

You are not using hydroxyzine as the primary treatment agent, Al. You are using it as an adjunct, and not for everybody.

Though I did not mention this, Dilantin has also been studied and used successfully for withdrawal states along with many other anti-convulsants. It sounds to me like you are using Librium as your primary agent for alcohol withdrawal with Dilantin as an adjunct. Nothing wrong with that. And you are using Dilantin as the primary agent with hydroxyzine as the adjunct for “hangover” level alcohol effects. Nothing wrong with that either. You are right that I personally would probably not treat a patient for withdrawal who only has a hangover. I would treat his pain with Tylenol or ibuprofen. The early symptom that gets people enrolled in my alcohol withdrawal program is a tremor.

A great trial that has never been done would be whether the combination of a benzodiazepine and and anticonvulsant like Dilantin or Tegretol works better at preventing progression to true Delirium Tremens than benzodiazepines alone. The place to do such a study is jails! Nowhere else treats as many people for alcohol withdrawal as we do!

Great Article,
We use a librium taper and oral thiamin based on their CIWA scores and presentation.
And because recidivism is so high in jails, if we have identified someone who has had significant problems in the past (like an ER sendout) we jump right on the librium taper, but augment it with additional benzo’s and IM thiamin for 3 days (IM/IV thiamin bypasses the liver and does a better job) then switching to oral thiamin. We have seen a huge decrease in ETOH related sendouts as a result of this.

You also metioned short acting benzo’s at the end of your article. I would really like to hear your thoughts on that as well. Xanax abuse is quite a problem for us locally and my medical director and I have struggled with how to best manage it. We used to stick anyone who said they used xanax on a librium taper as well, but it became commonplace for my opiate abuses to say they use xanax habitually in order to get librium to help the “sleep off” some of their opiate withdrawal issues. As a result, we have gone to a practice of placing patients on librium if we confirm they have a long term use hx that we can confirm (many states have prescriptions of abuse reporting systems that we can check), and if the patients say they buy if off the street and we cannot confirm habitual use, we monitor them using the same CIWA flowsheet, and start them if clinically indicated.
I am hoping you post a follow-up article regarding Benzo’s. As always, thanks for all your great blogs!

Thanks for the blog post I enjoyed reading it. Benzodiazepine withdrawal is quite tedious compared to alcohol withdrawal unless the patient is prescribed a very high dose, or abuse the benzodiazepines.

Asses CIWA scores. For initial control of symptoms a short acting benzo such as lorazepam is ideal followed by a protocol that includes a benzodiazepine with a long half life should be used. Ideally Tranxene in combination with folic acid, magnesium, thiamine, and multivitamin. Individuals undergoing ETOH withdrawal should be separated and monitored closely. Zofran, Phenegren, or Protonix can be used to treat corresponding nausea. Encourage hydration.

Thanks for your excellent blog. I was medical director of a 400-500 inmate county jail system for 20 years. Recently, at the request of an attorney, I reviewed a case in which a 71 year old male chronic alcoholic was brought into custody and given no thiamine. I wrote a report (with references documenting the consequences of thiamine deficiency) and testified to the state magistrate on behalf of the plaintiff (wife of the deceased). Case history:
2/15/11—Admitted to correctional facility – normal mood, affect, memory, intelligence, attention, concentration. Known chronic alcoholic
No gait abnormality noted
2/19/11 – Unsteady on feet, needs assistance for activities of daily life (ADLs)
2/22/11 – Unsteady gait
2/23/11 – Unsteady gait
2/24/11 – Incontinent of urine, admitted to hospital
2/24/11 – Needs assistance of 3 people. States “I am at the airport for the mail”
Confused, very slow mobility.
2/26/11 – Confused, unable to eat or drink
2/27/11 – To E.R., Confused, decreased urine output, fast breathing and heartbeat
Low blood pressure
3/7/11 – Transferred to ICU due to low blood pressure
3/21/11 – Unable to stand, incontinent
3/22/11 – Transferred back to custody from hosp. Unaware of surroundings, does not follow verbal direction, not eating, very weak
3/23/11 – Too weak to ambulate
3/24/11 – Delirium, disoriented, Stated he is “100 years old”, unable to stand without assistance.
4/1/11 – Admitted to Rehabilitation Hospital
4/17/11 – Expired

This patient was INITIALLY given thiamine on 3/6/11 as 100mg orally per day! He had no thiamine from 2/19/11 thru 3/5/11. At no time was he given parenteral thiamine. The state’s correctional medical “expert” claimed the patient had hepatic encephalopathy and not was not injured by thiamine deficiency. Tragically, the state’s magistrate dismissed the plaintiff’s case.

I am appalled that a state correctional facility and an E.R. could miss giving thiamine to a withdrawing alcoholic. Can you refer me to any references documenting that early thiamine is ESSENTIAL to the treatment of withdrawing alcoholics?

Wow! That dose of Xanax is so huge that I would start by questioning if it is accurate. Certainly no competent practitioner would actually prescribe that much Xanax? And would a competent pharmacy actually fill such a prescription? Alternatively, the patient could be telling you that he buys on the street and this is his verbal estimate of what he uses.
Bottom line, can you verify that his dose is accurate?

I just wanna say that this page is amazing & I’m elated that you lot are discussing this important issue in depth. I work in behavioral health & cannot tell you how pleased I am to find so many recovering addicts reporting that they were adequately medicated while locked up (recently, anyhow-several years ago I had major concerns). Keep up the amazing work!
